To all whom it may concern: 7

Be it known that ILEMANUEL JOHN Bor- LER, of the city of Peterborough,in the county of Peterborough and Province of Ontario, Canada, haveinvented certain new and-useful Improvements in Explosive- Engines; andI hereby declare that the following is a full, clear, and exactdescription of the same.

This invention relates to an explosive engine in which the gas isadmitted to the bore of the engine cylinder alternately on oppositesides of the piston head, and then exploded to drive the piston headalternately towards the opposite ends of the engine cylinder, ashereinafter described and specifically pointed out in theappendedclaims.

In the drawings: Figure 1 is a side elevation of an explosive engine.Fig. 2 is a vertical section through the explosive engine on a largerscale than in Fig. 1 Fig. 3 is a horizontal section taken centrallythrough the engine cylinder.

Like characters of reference refer to like arts throughout thespecification and drawln s.

he ends of the en ine cylinder 0 are closed by the cylinder hen s b andc and movable within the bore of the engine cylinder 11 between thecylinder heads I) and c is the piston head d. Centrally connected to thepiston head (if is the piston rod 6 which projects throu h a centrallylocated bore f in the cylinder head 0 and through the packing to);

protecting the engine cylinder from gas leakage through the bore f Fixedon the iston rod e on the outer side of the cylinder iead c is a crosshead It having guide rods 71 slidable through guideways attached to orforming part of the cylinder casing and located at the sides of theouter surface thereof. J ournaled in bearing boxes adjacent to thecylinder head bis the engine shaft Z providedwith cranks m and connectedto the cross head It and to the cranks m are crank rods 0. Mounted uponthe engine shaft Z between the crank m are balance wheels 1). Formedthrough the casing of the engine cylinder 11 adjacent to the cylinderheads I) and c are screw three ded bores q and 7', and fitted to thescrew threaded bores q andr are the inner ends of the mixin chambers sand t of the carbureters. The mixing chambers s andt are provided withinj ectors u and 0, each com risin a fuel chamber w a fuel inlet a forte fue chamber connected with the fuel su ply and a fuel outlet yconnected with the fiiel inlet and its respective mixing chamber. The

injectors a and t are provided with slideways' a" and b communicatingwith the fuel chambers w, and movable in the slideways a and I) aresuckers c and c coupled together by a link (1. e longitudinally movablein a slid'ewaydf, and actuating the pin 6 is an eccentric r0 g providedwith "an eccentric strap h which encircles the eccentric '11 mountedupon the engine shaft Z. During the revolution of the engine shaft Z,the eccentric t actua'tes. the eccentric rod g" to cause thereciprocation of the link d and the actuation of the suckers c and 0".At the ends of the engine Projecting from the link (1 is a pin' cylindera are exhaust ports j and 7: closed by interiorly opening valves 11' andm. The valves Z and m are connected with the piston head d by connectingmeans 0 and p. The exhaust ports 7" and 7c discharge into the muffler g.

In the operation of the engine, gas is admitted from the mixing chambers into the engine cylinder on the side of the iston head (1' adjacent tothe cylinder-head and when exploded by the igniter m moves the pistonhead (1 towards the cylinder head c. As the piston head d approaches thecylinder head 0 it actuates the connecting means 0' to open the valve Zand permit of the escape of the exploded gas through the exhaust port j.W en the piston head d has completed its stroke towards the cylinderhead 0 and cornmenced its return towards the cylinder head I) it forcesthe exploded gas through the exhaust port 3' and when thepiston head athas completed its return stroke towards thec'ylinder head b it moves thevalve Z to close the exhaust port \Vhen the piston head (I has completedits stroke towards the cylinder head 0 and .is about to commence itsreturn stroke towards the cylinder head b, the eccentric 'i actuates theeccentric rod 9 to move the sucker c and eject a selected uantity offuel from the fuel chamber w. of t 1e ejector '0 into the mixing chambert. When the piston head has passed the dotted line d on its returnstroke towards the cylof the gas within the mixing chamber t then ensthe valve e controlling the gas outlet of the mixing chamber t andenters the engine cylinder between the piston head (1 and cylinder head0. When the piston head (1 has passed the dotted line (1, the gas withinthe mixing chamber t.

the engine.,cylinder is'exploded and the piston head d is forced to theend of its stroke in the direction of the cylinder head 6. When thepiston head (1 has completed itsstroke in the direction of the cylinderhead I), it opens the valve m controlling the exhaust port 70 so thatduring its return stroke towards the cylinder head. 0 it will exhaustthe exploded gas through the exhaust port is.

As'the iston head (I completes its stroke towards t e cylinder head 0 itmoves the valve m to closethe port k to retain in the engine cylinderthe next charge of gas from As the piston he'ad approaches the cylinderhead I), the eccentric i actuates the eccentric rod g to move the suckerc of the injector 'u, to eject a selected quantity of fuel from the fuelchamber to into the mixing chamber s.' When the piston head (1 hascompleted its stroke in the direction of the cylinder head b and hasreturned to the dotted linej, it creates a partial vacuum Within theengine cylinder between itself and the cylinder head I) so that thepressure ,of the gas nwithin the mixing chamber s will automaticallyopen the valve g controlling the gas outlet from the mixing chamber 8into the engine cylinder. When the piston head d has passed the dottedlinef as it moves towards the cylinde head 6 the gas within the enginecylinder is exlr ed by the igniter 0 and the piston. head is driven bythe result of the explosion in the direction of the cylinder head 0.

As shown in the drawings, the engine shaft. 1 is located at one end ofthe engine cylinder, and the cross head it for the piston rod is locatedat the opposite end with the crank rods 0 connecting the cranks m of theengine shaft with the cross head at the sides of the engine cylinder. Bymeans of this construction, the-engine can be confined in a space eoualto the length of the engine cylinder pfus the fly wheels and the lengthof the stroke of the piston cross head. v Having thus fully described myinvention what 1 claim as new and desire to secure by Letters Patent is:
